Using a symmetric key encryption for large documents can be efficient, but sharing the key securely is important. This is where digital envelope comes into play. A digital envelope is a mechanism that uses public key encryption to exchange a symmetric key that is used to encrypt the data in the document. The symmetric key used for encrypting the document is wrapped by an envelope of encrypted data, which can only be decrypted by the recipient with their private key.
